Answer:
amino acids
anaerobic respiration
aerobic respiration
lungs
liver
kidneys
nitrogen
toxic
Explanation:
Excretion refers to the removal of waste products that is produced from amino acids metabolism.
Carbon dioxide is formed in living organisms in the process of both aerobic respiration and anaerobic respiration and can be removed from the body through lungs.
Urea is produced in the liver and then the blood is to be sent to the kidney and which is excreted from the body.
Urea is compounds of nitrogen which is formed from amino acids that contains toxic substances which the body does not need.

Describe the importance of a hypothesis in scientific inquiry.
Answer:
the basic idea of a hypothesis is that there is no pre-determined outcome. ... A key function in this step in the scientific method is deriving predictions from the hypotheses about the results of future experiments, and then performing those experiments to see whether they support the predictions.

Why does sexual reproduction process create offspring with genetic variation (different genes between parents and siblings)?
Answer:
Sexual reproduction process creates offspring with genetic variation because their are 2 parents unlike in asexual reproduction where there's only 1 parent. Since, there are 2 parents with difference in their DNA & genes the offspring too will have a variation.

Arrange the following steps to explain the process of protein synthesis inside the eukaryotic cell.
Answer:
Ribosomes are produced inside the nucleus, by the nucleus, then leave the nucleus through nuclear pores
Some ribosomes attach to ER whereas others move freely in cytoplasm
Ribosomes use mRNA to make proteins
Ribosomes synthesis proteins that are then placed in vesicles (sacs)
Proteins then move to the golgi apparatus where they get folded and carbohydrates and lipids attached to them
Fully active proteins leave the cell through cell membrane

13. Given the original DNA strand, which of the following would be the new, complementary strand
of DNA? ACTTACGCCGAT *
(8 Points)
CAGGCATAATCG
ACTTACGCCGAT
TCAATCGCCGTA
TGAATGCGGCTA
Answer:
TGAATGCGGCTA
Explanation:
The complementary DNA codes for A is T and for G its C
Answer:
TGAATGCGGCTA
Explanation:
Remember these are the complementary dna base pairs
adenine with thymine
thymine with adenine
cytosine with guanine
guanine with cytosine
so a would change to t
c to g
t to a
etc
after pairing each letter we would end up with
TGAATGCGGCTA

True or false Certified wood comes from trees grown in sustainable forests. Group of answer choices
Answer:
True.
Explanation:
Forestry can be defined as the art and science of creating, development, management, conservation and analysis of the living organisms such as plants, trees and woodlands existing in the forest. This is usually done so as to tap into the environmental benefits associated with the forests and to ensure the continuous existence of wildlife, plant growth and development.
Forest Management is a branch of forestry. The field of forest management typically deals with legal, administrative, financial, economical, technical and social aspects of a forest so as to facilitate the smooth running and operation of the forest reserve.
A sustainable forest can be defined as a forest management process which typically involves the plantation of seedlings to replace trees that are being cut down. Thus, sustainable forestry is mainly focused on keeping the natural forest alive.
Generally, certified wood comes from trees grown in sustainable forests i.e responsibly managed forests.
Hence, certified woods are gotten from trees that were harvested in accordance with sustainable forestry.
Most biology textbooks prior to 1990 listed the major function of ribonucleic acid (RNA) as transferring information from DNA to make proteins. In late 1989, Thomas Cech proposed that RNA had a second major function: as a catalyst for chemical reactions that occur inside the cell. His discovery surprised most scientists and caused the rewriting of many chapters in biology textbooks. What aspect of the scientific process does this best illustrate?
Answer:
The correct answer would be - overgeneralization of a hypothesis.
Explanation:
In this case, the scientist uses to think and listed the transferring information from DNA to make proteins as the main and major function of the RNA until Thomas Cech proposed that it is the second most important catalyst that takes place in the cell and catalyzes cell's chemical reactions.
This illustrates major aspects of the scientific process: overgeneralization of a hypothesis as RNA is not just a molecule that assists and transfers the information but new evidence found it has catalytic activity also.
